WWI: The war where US got in, because of a submarine thingy, right? plain stupidity, but rich and famous they became the us government.
WWII: arrogant acts from US. only got in to the war because of their own ass getting whooped by japanese airforces and marine. then they realised how ''strong'' they were, and got into the whole '' lets rule the world'' point of view. And another thing: European guy: '' us help us'', american guy:'' nah, not yet, we wait till they burn pearl harbor''.
some time later
american guy and english guy talks together and crushes most of hitler's army.
Vietnam: '' lets go kill some of these creeps with weird eyes, and oh, they are pretty beautiful too. so why dont we **** their wifes and ruin their economy?
some time later
oh no. we ''lost'' the war, and now they want to get to america! HURRY lock all your doors!
iraq: pluses: who am i trying to fool? only plus in that war was the remove of saddam. negatives: ''three hours later''
